A control apparatus for internal combustion engines, which generates an adjustment path on the path of an adjustment member which is proportional to the air mass supplied to the engine. The control apparatus contains a counterpart pressure chamber sealed off from the outside and separated in a pressure-tight manner by an adjustment diaphragm from a first pressure chamber exposed to induced air pressure. A pressure source generating a reference absolute pressure which is constant under all operating conditions is connected to the counterpart pressure chamber. Consequently, the apparatus performs the function of a charge pressure stop equipped with a diaphragm box. The air reservoir of an air pressure brake system, a reservoir charged with the exhaust gas counterpressure or charge air pressure, or a vacuum pump can serve as the pressure source, and an absolute pressure controller controls the reference absolute pressure prevailing in the counterpart pressure chamber.
